setting is AGM Battery; the controller will automatically memorize your battery type
setting.

Li-ion battery shown in LCD indicates 3-SERIES Li-ion battery shown as below:

-- Lithium Cobalt Oxide LiCoO2 (LCO) battery

-- Lithium Manganese Oxide LiMn2O4 (LMQ) battery

-- Lithium Nickel Manganese Cobalt Oxide LiNiMnCoO2 (NMC) battery

-- Lithium Nickel Cobalt Aluminum Oxide LiNiCoAlo2 (NCA) battery

LiFePO4 battery shown in LCD indicates Lithium Iron Phosphate battery, LFP battery.

LTO battery shown in LCD indicates Lithium Titanate Oxide, Li4Ti5O12 battery.

Caution: Incorrect battery type setting may damage your battery.

When the controller powers on, the unit will run self-qualify mode and automatically show

below items on LCD before going into charging process

Self-test starts, digital meter segments test
